Bad Signatures when using check-sigs

[David Tomaschik]

When executing gpg --check-sigs, there are reports of "bad
signatures."  What makes a signature "bad"?  For example, on a key I
signed that has several UIDs, one of my signatures on one UID is
reported as bad, but the rest are fine.  I looked in the docs, but
didn't find anything... hope I'm not missing something obvious.
